What does the church fund?
- potlucks
- a church building
- some missions (although from what little I know about it, much of this is actually funded by the family of the young (or old) person going on a mission, not the church).

Now I am sure that the list for what the church funds could be longer - but so could the list of what NASA funds. Seems to me that the federal government is doing much more with its 14% than Glen's church is doing with its 10%. Maybe, if Glen is really that sore about taxes, he should just join a cheaper church.
